\n" ); document.write( "If events A and B are independent, then we can say:
\n" ); document.write( "P(A and B) = P(A)*P(B)
\n" ); document.write( "P(A and B) = 0.5*0.6
\n" ); document.write( "P(A and B) = 0.3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If A and B were dependent, then we cannot use that formula.
\n" ); document.write( "Instead we would have to say something like
\n" ); document.write( "P(A and B) = P(A)*P(B given A)
\n" ); document.write( "or
\n" ); document.write( "P(A and B) = P(B)*P(A given B)
\n" ); document.write( "Many math textbooks will replace the word \"given\" with a vertical bar.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since the instructions do not make it clear if A & B are independent or not, there is unfortunately not enough information to answer this problem.
